20.04 - Logitech MX Keys won't pair with Bluetooth
Solution 1
I fixed it, installing some missing firmware. All I had to do is run this command:
cd /lib/firmware/brcm && sudo wget https://github.com/winterheart/broadcom-bt-firmware/raw/master/brcm/BCM20702A1-0a5c-21e8.hcd
and unplug and plug again my bluetooth dongle
Solution 2
I had the same kind of issue with a Lenovo keyboard. basically I could enter the pin code but after hitting return nothing happened.
$bluetoothctl
[bluetooth]# agent KeyboardDisplay
[bluetooth]# default-agent
[bluetooth]# scan on
[bluetooth]# pair <MAC-address>
Attempting to pair with <MAC-address>
[CHG] Device <MAC-address> Connected: yes
[agent] Passkey: xxxxxx
[agent] Passkey: xxxxx
[agent] Passkey: xxxx
[agent] Passkey: xxx

Authorize service

It looks like the last step [agent] Authorize service
is not shown in the GUI

I am using Ubuntu 20.04.1 and I am trying to pair my MX Keys keyboard via Bluetooth.
I start the process with the Bluetooth control panel, and I get stuck in this window.
Even though I type the right PIN and press ENTER, still the process does not complete. In fact, it gets stuck in that mode, with the PIN window unable to be closed.
I have also tried using "Blueman" with a similar result. I start the "Setup" process, and this is what I get in the end.
I have also tried with
bluetoothctl
➜ bluetoothctl connect CB:DD:B4:5C:4E:E3 Attempting to connect to CB:DD:B4:5C:4E:E3 [CHG] Device CB:DD:B4:5C:4E:E3 Connected: yes Connection successful ~ took 8s ➜ bluetoothctl trust CB:DD:B4:5C:4E:E3 [CHG] Device CB:DD:B4:5C:4E:E3 Trusted: yes Changing CB:DD:B4:5C:4E:E3 trust succeeded ~ ➜ bluetoothctl pair CB:DD:B4:5C:4E:E3 Attempting to pair with CB:DD:B4:5C:4E:E3 [CHG] Device CB:DD:B4:5C:4E:E3 ServicesResolved: yes [CHG] Device CB:DD:B4:5C:4E:E3 ServicesResolved: no [CHG] Device CB:DD:B4:5C:4E:E3 Connected: no Failed to pair: org.bluez.Error.AuthenticationCanceled ~ took 30s
What could be done about it, to get it to work?
UPDATE
I have managed to get a PIN with
bluetoothctl
if I reset Bluetooth in my PC, but even if I type the PIN, the authentication fails. It is as if it was ignoring what I type...[bluetooth]# pair CB:DD:B4:5C:4E:E3 Attempting to pair with CB:DD:B4:5C:4E:E3 [CHG] Device CB:DD:B4:5C:4E:E3 Connected: yes [agent] Passkey: 610148 [CHG] Device CB:DD:B4:5C:4E:E3 Connected: no Failed to pair: org.bluez.Error.AuthenticationCanceled

Gardener over 2 yearsExtremely helpful! Once I ran this, I started getting the codes needed to type into my MX Keys keyboard. I am guessing the solution was the "agent KeyboardDisplay" plus the "default-agent".
